PLANING-MACHINE.

Specification of Letters Patent.

Patented Sept. 16,1913.

I which the following is a specification.

My invention relates to planing machines arranged for planing wood.

It is the object of my invention to provide novel means for adjusting either end of the lower cutter-head support up or down indeproved device.

pendently for alining the lower cutter-head with the material support, and for simultaneously adjusting both ends of the lower cutter-head support to elevation with relation to the material support; and, further, to provide novel means for clamping the cutter-head support in adjusted positions.

The invention will be further readily understood fromthe following description and claims, and from the drawings, in which latter:

Figure 1 is an end elevation of my ini- Fig. 2 is a vertical section of the same, taken on the irregular line 22 of Fig. 1. Fig. 3 isa cross-section of the same, taken on a line corresponding to the line 33 of Fig. 2. Fig. l is a horizontal section of the same taken on the irregular line l l of Fig. 1. Fig. 5 is an enlarged sectional detail, showing the adjusting means for the cutter-head support, taken on the line 22 of Fig. 1; and, Fig. 6 is a rear perspective view of the cutter-head saddle.

11 represents the frame of a wood planing machine, which may be of suitable construction, and have one or more horizontal cutterheads and suitable upright cutter-heads and feeding devices mounted therein, the feeding device being arranged to feed the material in the direction of the arrow 42.

12 represents a lower cutter-head.

13 is a material supporting table in advance of the lowercutter-head, which may be provided with any suitable adjusting means (not shown) for lowering or, raising the table and adjusting the same toward and from the lower cutter-head in suit-able manner. a j

. 14 is a material supporting table in rear of the lower cutter-head.

The lower cutter-head shaft is mounted on and adjustable with a support by which its position is determined with relation to the material supporting parts in the machine, and novel means are provided for clamping the support in place after adjustment. The support in the present exemplification comprises a plurality of parts, exemplified as a yoke and a saddle. The lower cutter-head is rigid with a shaft 15 having suitable driving pulleys 16 thereon and journaled in bearings 17. The bearings are shown on a yoke 18 longitudinally slidable crosswise of the main frame of the machine and guided by a guide 19 on a saddle 20.

I provide novel means for adjusting either end of the lower cutter-head up or down, so

as to aline the lower cutter-head with the material supporting face of the material supporting part of the machine, so arranged that either end of the lower cutter-head ma y have adjustment imparted thereto without adjusting the other end thereof, so that if only one end of the lower cutter-head is in incorrect position, the incorrect end only need be adjusted into correct position, and for simultaneously adjusting both ends of the alined cutter-head up or down so as to bring the same to proper elevation with relation to the material. supporting part of the machine. The cutter-head yoke is provided with side guide-faces 21, 22, which coact respectively with side guide-faces 23, 24, on a rigid part of the frame. The cutter-head saddle is provided with side guide-faces 25, 26, which coact with the side guide-faces 23, 2 1. Portions of the side guidefaces 25, 26, are on depending cheeks 27, 28. Portions of the side guide-faces 23, 24, are on cheeks 29 on the rigid part of the frame, the cheeks 27 cooperating with the cheeks 29. These guide-faces position the cutter-head yoke and saddle laterally for correctly positioning the same lengthwise of the main frame.

For maintaining the lower cutter-head support in longitudinal position, that is, in correct crosswise relation with the main frame, and permitting ready raising and lowering of either end of the support throughout its various height positions, I provide a guiding slot 35, shown in one of the cheeks 29, withwhich a positioning pin 36 secured in one of the cheeks 27 cooperates, the portion of the pin received in said slot filling the space between the walls of said slot, thereby endwise positioning the lower cutter-head support, permitting tilting thereof during adjustment, and enabling either end thereof to be raised or lowered inde pendently.

37, 38, are adjusting screws at the re spective sides of the main frame corresponding to the respective ends of the lower cutter-head support. These adjusting screws are respectively journaled in bearings :39, 40, 011 the main frame and held endwise therein between collars 41 and gears 42, 43, shown as worm-wheels, on said respective screws. The said adjusting screws respectively have threaded connections with the saddle in threaded bearings 44, 45, in said saddle.

46, 47, are gears, shown in the form of worms, with which the respective wormwheels 42,743, cooperate. he worm 46 is fast on a hollow sl aft 48 which is journaled in a bearing 49 in the main frame. A hand operating device 50, shown as a hand wheel, is on the hollow shaft. The hollow shaft is held endwise in the bearing 49 by the hub of said hand-wheel and a shoulder 51 on said hollow shaft. One end of a shaft 52 passes through the bore of the hollow shaft. Each of these shafts is rotatable with relation to the other of said shafts. The other end of the shaft 52 is journaled in a bearing 53 in the frame. The shaft 52 has the worm 47 fast thereon. The shaft is held endwise by having the worm 47 received against the bearing 53 and being provided with a shoulder 54 received against the hollow shaft 48. A hand operating device 55, shown as a hand-wheel, is on the shaft 52 for rotating the same.

Either shaft may be rotated independently for adjusting either end of the lower cutter-head to elevation, and slight axial movement is permitted between the operating devices for the respective adjusting screws for placing said operating devices in independent orrigid relations. For this purpose the hand-wheel 55 has spline connection 56 with the shaft 52.

A friction clutch 61 is located between the gagement, the turning of the hand-wheel 62 for effecting thisclutching engagement urging relative axial movement between said hand-wheel and hollow shaft, and thereby Connecting th same ri i ly, s hat when said clutch is in engagement the worms-46, 47, will be rotated simultaneously upon the rotation .of either of the hand-wheels 50, a V TWhen said clutch is 1n disengaged relation,

efiected by rotation of the hand-wheel 62 in the opposite direction, either end ofthe cutter-head support may be raised orlowered independently of the other end of said support, so that if either end of the cutterhead is out of correct elevation with relation to the plane'of thesupporting surface; of the material support, that end only need be raised or lowered, or either end of the cutter-head maybe raised orlowered inde? pendently ofthe other, for positioningthe cutter-head in alinement with the material supporting surfacexof the material support,

so that when said cutter-head is in alinement but at incorrect elevation, the clutch 61 may be brought into clutching relation a clamping action upon the respective ends of the cutter-head support and operated by means of a single shaft 73fthe wedge-faces of said wedges at the respective ends of said cutter-head support slantin in directions opposite to each other,and the longitudinal positions of said wedges being unfixed, so that the wedging action of one of said wedges will be dependent on the wedging' position of the other of said wedges. Thus the operating'shaft is provided with threaded portions 74, 75, forming respectively right and left hand screws, with. which respectively the corresponding threaded bores 76, 77, in said wedges coact. The wedges are located in recesses 78, 79, in a rigid part of the frame, the said recesses being provided with oppositely slopingwedge-faces 80, 81, with which wedge-faces 82, 83', of said wedges coact. Contact faces 84, 85, of said wedges are presented to the coacting face 21, of the cutter-head support. These contact and coacting faces are preferably parallel "with each other and with the guide between the cutter-head yoke and the cutter-head saddle, so that wedgi ng between the wedges and said r gid part of the frame and cutter-head yolie may be effected irrespective of the longitudinal position of the V cutter-head yoke on the cutterhead saddle, or the position to which either end or both ends of said cutter-head yoke be ele vated, and for permitting lengthwise shifting of said yoke upon very minute disengaging movement between said wedges.

The shaft 73 is provided with'suitable turning means, exemplified as a pin"8 6, a suitable turning device, such as a crank, being arranged to be received overthe end of the shaft and tomake engagement with said pin for turning said shaft. The clamping shaft 73 is provided with collars 87 88, fast thereon, normally spaced from a bean ing 89 on the frame in which said shaft rotates. If either wedge should become lodged prior to its clamping action, one of said collars will engage the bearing for preventing undue axial movement of the'clamping rod in either direction and avoiding turning of either screw thereon out of the threaded bore of either wedge.

Ihe wedging act-ion of the clamping means for the lower cutter-head sup-port is exerted in a direction which is perpendicular to the direction of its adjustment, and the clamping action is exerted simultaneously and to equal degree at the respective ends of the cutter-head support, so that a firm clamping action throughout the length of the cutter-head support and rigid positioning of the cutter-head support may be effected without disturbance of adjustment. For aiding in preventing disturbance of adjustment I provide a pluri-part cutter head support, the parts of which are in superposed relation, and connect the adjusting means with the lower of said parts and the clamping means with the upper of said parts, thereby further removing the clamping means from positive action upon the adjusting means.
